Mercer Mass Timber and CLT Toolbox Launch First-of-Its-Kind Digital Integration to Advance Mass Timber Adoption in North America

Collaboration allows engineers to specify MMT’s CLT and glulam products directly in design workflows, advancing mass timber as a mainstream building material

Spokane Valley, WA, July 17, 2025 (GLOBE NEWSWIRE) -- Mercer Mass Timber (MMT), a leading manufacturer of sustainable timber building materials and a subsidiary of Mercer International Inc., announces a strategic partnership with CLT Toolbox, a structural design software platform built specifically for mass timber buildings. 

The collaboration marks a major step toward making mass timber a mainstream construction material by connecting advanced digital workflows with real-world manufacturing capabilities. By embedding product-specific, code-compliant design tools into a digital platform accessible to structural engineers worldwide, the partnership removes long-standing barriers that have historically slowed the adoption of mass timber as a mainstream building solution.

“Our collaboration with CLT Toolbox is about facilitating digital design in the realities of mass timber fabrication,” said Ricardo Brites, PhD, Director of Engineering & VDC at Mercer Mass Timber. “It’s a smart, integrated and accessible approach—and exactly the kind of alignment the industry needs.”

This is one of the first integrations of its kind in North America and signals a broader shift toward digitized, scalable mass timber construction. By simplifying design, manufacturing, and installation, MMT and CLT Toolbox are using advanced technology to remove complexity from workflows and accelerate the transition to low-carbon building systems.

This integration provides benefits throughout the building lifecycle:

• For engineers: It offers calibrated, best-practice design tools that reduce guesswork, enhance design confidence, and streamline approvals.
  
  
• For architects and developers: It ensures cost predictability, constructability, and compliance are addressed early, improving timelines and reducing downstream rework.
  
  
• For the industry at large: It represents a leap forward in the digitization and scalability of mass timber construction.

“The world is ready for low-carbon construction—but technical bottlenecks are holding us back,” said Adam Jones, CEO and Founder of CLT Toolbox. “Once we remove those, mass timber has everything it needs to lead the future of building.”
